The timing chain tensioner on my bmw 2014 c650gt malfunctioned and destroyed the engine in my scooter. I am uninjured. Luckily. Stalled as I arrived at my destination and would not restart with very loud rattling noises from the engine compartment. I'm quite upset after seeing the attached recall from 6 years ago and wondering why the dealership where I purchased the vehicle, bmw of cambridge, ma , did not notify me of this. It would have prevented the unfortunate incident from happening.

Vehicle stalled while driving at low speeds or at idle. The vehicle also stalled while making a left turn at an intersection and would not immediately restart. There was a recall on this model affecting years 2013 and 2014 this is a 2014 model. This is being referred to you because I was within 6 feet of being killed for this problem and when I mentioned it to the service department at bmw I was told it needed a $2600 24,000 mile service. It is the camshaft chain tensioner, I know this because bmw sent a letter to you on may 14th 2014 in a 3 page document stating that this is a serious issue and that bmw would be issuing a recall to repair the issue. I don't care about the $2600 for the service, however, I do care about being in danger of being killed because the engine decides to stall on the freeway or while making a turn on an intersection or even worse riding close to a cliff and riding over the side because of loss of power. The letter was addressed to nancy lewis associate administrator of enforcement from samuel campbell iii, department head ,safety engineering and its.

My 2016 bmw c650gt scooters' mechanical timing chain tensioner failed, allowing my timing chain to jump, causing my valves to slam into my pistons which bent the valve stems, causing a repair cost of $3800.00 u.s. Had this happened while I was still on the freeway (had just exited I-5 in seattle and was starting to re-accelerate to 25 MPH on 45th ave w. When the timing chain slipped causing a very loud clacking noise, followed by a stall and the inability to restart) this could have easily caused a dangerous accident and serious harm, if not death to myself, or any rider in this situation. This is a known issue by bmw, and was a recall on earlier models (2013 & 2014) and remedied by replacing them with a hydraulic timing chain tensioner, however bmw continued to manufacture later bikes using the mechanical timing chain tensioner. A quick google or facebook search of bmw c650gt owner/ groups/forums, turns up many discussions from owners all over the world complaining about this exact same issue. In some cases, bmw has paid 100% of the repair, but in many bmw won't pay anything. In my case they are paying 50% however they should be paying 100% of the repair bill as this known issue. Bmw is not exactly consistent in the way that they are handling these repair costs and its time they do what is right, or be forced to do what is right. It's dangerous for any vehicle to stall in the middle of the freeway but it's extra dangerous for a motorcycle rider if this happens while moving in fast traffic on a highway. This is a dangerous issue for any bmw c650gt owner w/ a mechanical timing chain tensioner installed on their bike. I've read facebook posts from owners with 2017 c650gts whose bikes were manufactured w/ the mechanical timing chain tensioner! How can bmw do that if they've recalled this issue on earlier years and fixed the issue with hydraulic tensioners? Help!

Scooter stalls when coming to a stop, or turning at a slow speed. It appears to happen after the scooter has warmed up. Stalls at intersections causing near misses from cars behind thinking I'm pulling away from intersection when bike stalls.

Stalling in traffic at stop light/sign, and engine idles down and stalls. Sometimes stalls when starting off after a stop at a stop light. Had it checked at dealer, issue continues. Happens a few time during my daily commute.

The engine stalls when slowing for a stop or for a tight turn. It can then be restarted, but the idle may be inconsistent and can affect the CVT automatic transmission when decelerating in traffic. I purchased this motorcycle new in march (3/25/16). When I drove it home from the dealership and called them about the problem with stalling, they had to trailer it to the shop for diagnosis and testing due to safety concerns. The local dealership has had this bike in the shop for over a month, "researching" the issue with the factory technical reps.

Vehicle stalls at low speeds. Will surge at low speeds. Will stall out when doing less than 15 MPH or giving no throttle. Will stall when vehicle is stopped for traffic or parking it. Has been to the dealer twice for repairs with negative results. They claim it's a computer issue. They fail to repair it.
